講稿 21/21 技術分析真荒謬
Lecture 21/21 Technical analysis is ridiculous
許多人股票喜歡跑短線,以為台股交易成本低,
手續費僅0.1425%,證交稅0.3%,
其實不然,實際算一遍給大家看。
故事的起源是2003年我在北投上課時,
有一位同學叫阿平,從南投到北投來上課。
Many investors enjoy engaging in speculative trading, believing that the trading costs for Taiwan stocks are very low. This is due to the commission fee of only 0.1425% and the transaction tax of 0.3%. However, this assumption is not entirely accurate. Allow me to provide a detailed calculation. The story behind this issue dates back to 2003 when I was teaching in a classroom located in Beitou. One of my students, named Aping, traveled from Nantou county to attend my class in Beitou district.
阿平上課時很勇於舉手發問,
一直用技術分析觀點來挑戰我的巴菲特,
本班歡迎同學學過邪門歪道的功夫儘量使出來沒關係。
下課時跟阿平聊了一下,
他曾花了10萬元在台中拜技術分析高人為師,
自認為技術分析很厲害。
我一聽很不是滋味,因那時巴班學費才5,000元,
心想差距怎麼如此大?
堂堂武林第一大門派的巴菲特班,學費5,000元,
什麼鳥不見經傳的技術分析學費10萬元。
Aping enthusiastically raised his hand to ask questions and even challenged Buffett from a technical analysis perspective during the class. As an open and inclusive classroom, we welcomed all challenges and discussions.
After class, I had a chat with Aping. He mentioned that he had spent NT$100,000 to learn technical analysis from teachers in Taichung and felt confident in his skills. I was taken aback by the large discrepancy between his tuition and mine, which was only NT$5,000. It made me wonder why the gap was so significant. While Buffett is regarded as the first investment master, technical analysis tuition seems to be significantly overpriced and unranked in comparison.
上完課後同學一起通伊媚兒,
當時尚無討論區,用伊媚兒在討論。
阿平的伊媚兒都是前面哈拉幾句之後最後就跑出3個號碼,
問我這3家公司可否好很久?
那3個號碼都是新上櫃、獲利不到5億元的公司。
心想這傢伙故意來搗亂,
上課時特別強調上市櫃滿2年,獲利大於5億元,
阿平問的全是相反的公司。
那3家公司我完全不認識,
當時初為人師還充滿教學熱誠,
花了一下午查資料、做研究,
回信回去,1、2、3,
1、2、3,
1、2、3,
寫了9大點回去。
After the class, the students communicated with each other through emails since there was no discussion forum available at the time. In one of Aping's emails, he included three numbers at the end and asked whether these three newly listed companies were viable for the long term. However, all three companies had profits below NT$500 million, which did not meet the criteria I had emphasized in class, which was a two-year presence in the market and a profit exceeding NT$500 million. I suspected that Aping was deliberately trying to stir up trouble. As I was still passionate about teaching at the time, I spent an entire afternoon researching and gathering information on these three companies. I came up with nine points in my response and replied to Aping with the numbers 1, 2, and 3 written three times. I hoped that this would clarify my stance on the matter and provide valuable insights for the rest of the students.
2天之後來第二封信,又是哈拉幾句之後3個新的號碼出現,
我再次花一下午研究寫了9大點回去。
現在同學若要這樣做我就不理你了,
因為已沒了教學熱誠,只剩收學費的熱誠。
昨天心情比較嗨,今天就混了,
因今天沒學費可收。
同學教我「那還不簡單,就今天收一半學費,隔天再收另一半,
這樣就每天有錢收!」
我說「才不像你那麼笨咧,這樣第二天就沒人來了,」
「我應該第一天收 1 萬元,隔天退差額」
Two days later, I received a second letter from Aping, which included three new numbers after a few sentences. I spent another afternoon researching and writing down nine key points to reply. If my students were to act in the same manner, I would ignore them because my passion for teaching had been replaced by a passion for collecting tuition fees. Yesterday, I was in high spirits, but today I felt demotivated since there were no tuition fees to collect. One of my students suggested, "It's simple. Collect half of the tuition fee today and the other half tomorrow. This way, you can collect money every day!" I replied, "I'm not as foolish as you. If I did that, no one would show up the next day. Instead, I should collect the full tuition fee of 10,000 NT dollars on the first day and refund any remaining balance on the following day."
隔了2天之後又來了第三封信,我就抓狂,
不回了直接打電話問他問真的還是假的?
「問真的啊!」阿平答,
「你怎麼可能有那麼錢買那麼多股票?」我不解
「第一封信那3支股票買了沒?」,
他回「買了,已經賣了。」
「蛤!那麼快,第二封信的3支呢?」我再問,
「也賣掉了」他應,
我更吃驚「那第三封信這3支應還沒買吧?因為我還沒回。」
阿平一付輕鬆狀「沒關係,也賣掉了。」
好里佳在,第三封沒回,
才知道原來他每2到3天就換股一次。
Two days later, the third letter arrived, and it drove me crazy. Instead of replying via email, I called him and asked if he was serious about these stocks.
"Absolutely," Aping replied.
"How do you have so much money to buy all these stocks?" I inquired.
"Did you buy the three stocks from the first letter?" he asked.
"I bought and sold them," he replied.
"Oh! That was fast. What about the three stocks in the second letter?" I asked again.
"I sold those too," he responded.
I was even more surprised. "Did you buy the three stocks in the third letter yet? I haven't replied yet."
"It's fine, I already sold them," Aping said casually.
Luckily, I didn't reply to the third letter, and I found out that he changes his shares every 2 to 3 days.
問他跑來跑去有賺到錢嗎?
阿平表示「有,每年大概賺個幾萬元。」
他說他每年成交額上億元,
成交額上億元本金不用多少錢,100萬元即可,
每周買賣一次,成交額就上億元(=100萬x2x52)。
他覺得很奇怪過年時營業員都會送他禮物,
我說「當然,因為營業員賺得比你多。」
成交額1億元,手續費0.1425%,
營業員和券商即賺14萬元,比阿平賺幾萬元多。
「可是我賺最少,才5,000元,」我怒吼著
「工作卻最多!」
I inquired if Aping made money from speculative trading, to which he replied that he earns tens of thousands of Taiwan dollars annually. He claimed to have a turnover exceeding NT$100 million, which isn't difficult to achieve with a principal of just NT$1 million. With weekly transactions, turnover would surpass NT$100 million (= 1 million x 2x52). Aping was surprised that his broker gave him gifts during the New Year, but I explained that it's because the broker's income exceeds his. With a turnover of NT$100 million and a commission fee of 0.1425%, brokers and securities companies earn NT$140,000, more than Aping. I grumbled that I earn the least, only NT$5,000, but Aping remarked that it's the hardest.
當年我真的充滿教學熱誠
「來,幫你算一下一年的交易成本多高?」
阿平是2-3天買賣一次,
放寬假設每2周買賣一次,
每月買賣2次,1 年玩24次。
Back then, I was really enthusiastic about teaching. "Come on, let me help you calculate how high the transaction costs would be for a year?" Aping trades once every 2-3 days. Relaxing the assumption that trades occur every 2 weeks, buying and selling twice a month, and playing 24 times a year.
手續費0.1425%,買賣都要付,
1 年24次,一年手續費即6.8%
手續費:0.1425%x 2 (一買一賣) x 24 = 6.8% 
The commission fee is 0.1425% per transaction, and it must be paid for each trade. With 24 trades a year, the total commission fee for one year would be 6.8%.
Commission fee: 0.1425% x 2 (one buy and one sell) x 24 = 6.8%
證交稅給政府的0.3%,賣時才課,
1 年24次,一年證交稅7.2%
證交稅:0.3% x 24 = 7.2% 
The transaction tax is 0.3%, which is a government tax that is only charged upon selling.
With 24 transactions a year, the annual tax payment is 7.2%.
Transaction tax:0.3% x 24 = 7.2%
1 年的交易成本,手續費+證交稅等於14%。
同學知道我一年的交易成本多少嗎?
我2008年買台積電、大統益抱到2017年都沒賣,
一年交易成本是萬分2不到。
The total transaction cost for one year, including commission fee and transaction tax, is 14%. Do you know how much my annual transaction cost is? I purchased TSMC in 2008, and I did not sell it until 2017. The transaction cost for one year was only 0.02%, which is extremely low.

做這麼短必定融資,
融資是出4元可買到10元,成本將暴增為35%(=14% x10/4),
加上融資利息,融資利率6%,
融資利息占本金9%(=6% x 6/4),
總共的交易成本44%(=35%+9%),
未玩之前先賠掉一半,這樣怎麼可能賺錢。
It is necessary to finance speculative trading, which involves paying NT$4 to purchase NT$10 worth of stocks. The transaction cost will skyrocket to 35% (=14% x 10/4). In addition to this, there is also financing interest which is charged at a rate of 6%. This financing interest accounts for 9% of the principal amount (=6% x 6/4). Therefore, the total transaction cost is 44% (=35% + 9%). This means that half of the investment is lost before even starting the trade, making it very difficult to make any profit.

台股證交稅是世界屬一屬二的高,
之所以這麼高是因當年郭婉容課證所稅失敗,
造成股市19天無量下跌,
政府為了善後把證所稅取消併入證交稅,
由證交稅由0.15%增為0.3%。
台股證交稅裡已包含證所稅,
請蛋頭學者和政客們勿冤枉投資人賺了錢不繳稅。
Taiwan has the highest transaction tax rate in the world. In the past, former Minister of Finance Wanrong Guo implemented a capital gains tax, which led to the stock market crashing for 19 consecutive days. To rectify the situation, the government abolished the capital gains tax and increased the transaction tax rate from 0.15% to 0.3%. As a result, the capital gains tax was incorporated into the transaction tax. Therefore, egghead scholars and politicians should not blame Taiwanese investors for not paying taxes on their earnings. We have paid transaction tax.

在這種制度下,跑短線投資人最不利,
沒賺到錢卻在仍然在繳證所稅。
Under this system, speculative traders are at a disadvantageous position as they have to pay capital gains tax even before making any profits.
