Quote from TM_Direct:
OK....do the the math.....if he made 15% or better on 49 trades......lets assume he lost 100% on the other 5 trades......Im going to go out on a limb and say he has a pretty good over return,,,true or false?
When I took a "snapshot" of his alleged positions last November, the average term was 113 days. The average return was 12.6%. 113 is approx. 47% of the annual number of trading days, which would make his annual return about 26%, if he continued with the same results. That's a cautionary 'if', because as gains/losses mount and decrease, and as his holding time changes from trade to trade, obviously the annual return will differ. But if you peg it as of 11/10/03, we could state that that rate of return would yield about 26%, wins and losses combined. That's not to say that's what he does every year, again, that's just a snapshot based on holdings at that moment. You may feel 26% is the pinnacle of achievement, others may not think so. Regardless, a big, big extra factor with that method is the constant need for capital infusions (there were 14 additional infusions) to capture new opportunities (because capital is tied up indefinitely while holding declined positions), which makes the investing style more expensive as it creates an unseen cost. Additionally there's a secondary unseen cost because capital kept out of use in what could be gainer opportunities in the interim prevents booking those profits.
Now, if you're running a mutual fund and you've got cash coming in by way of customers, that's one thing to hold said losing positions. But if you're just a guy and gotta take the new capital out of your paycheck or savings, then it's not the best plan for family money management, and wifey is sure to complain about your pulling it out.
Even fellow Wharton MBA'er Lynch, who also didn't believe in stop losses, did believe in and practiced trade rotation: getting out when the 'story' or fundamentals changed, rather than at a predetermined percentage or price point, and putting the capital to work in a better opportunity, rather than keeping capital in holding losses till target or bust. Even then, he saw a number of holdings bust, but given that he held 1400 positions in America's greatest bull market ever, he could still come out ahead.
A side note. The thing about basing investing on FA, and then declaring as a result of that, '15% in 4 to 6 weeks', is a dichotomy of FA and TA. While FA may base how a stock is valued, supply/demand, and its perception of that supply and demand, is what causes a stock to be priced differently every day and throughout the day, right? Otherwise, given that the fundamentals haven't changed over the period, the stock's price shouldn't change either. So why would any FA lead one to determine that the stock will now gain 15% in a certain time period, simply because it's now made an appearance on a stock screen? That strikes me of TA.
