I would not get hung up over the number 2400%. If the quote in this thread is accurate, he took say $3000 and turned it into $30000 over a period of a two years ending January 2000. The Nasdaq almost tripled in that period. I am sure many people were able to achieve 10x returns in that period starting from a small stake, particularly if they used aggressive instruments like options. Doing an additional 140% during 2000 would not have been that extraordinary either - I did 68% in my trading account.
Of course, many more didn't achieve these returns, but the results quoted do not prove that his method is enduringly superior. His results are not to be sneered at. They are great, but are they repeatable?
I remember when I was trading in the early 80's with a small stake of about $6k, I tripled my money in a few months, but I recognized it was a small numbers effect. I would never expect to do it now with the size of portfolio I run. You simply tend to trade differently with a small account unless you have nerves of steel and a true gambler's mentality.
I have extracted this quote from his web-site:
".....if a large percentage of a stock's ownership changes hands while the stock's price is moving sideways then a big move in price will probably soon occur. These ideas once understood make such common sense as to make one wonder how they were overlooked for so many years."
Well I have not read the book and don't intend to, but it does not make much common sense to me. In the types of volatile markets we have been having over the past several years it has been very common for stocks that have been trading sideways to make explosive moves when they have broken out of the range they have been trading in. These moves tend to be more explosive for stocks with a thin float, which are precisely the type of stocks more likely to turn over their floats while trading in the range.
For larger cap stocks, it will take longer to turn over their float so only those that have established a trading range over a long period of time would likely qualify. Stocks that break out of long, clear bottoms, tops and consolidation ranges also tend to attract attention.
The float turnover concept sounds like an artificial construct to me, rather than a revolutionary technical analysis breakthrough. I would much sooner define the limits of the trading range on the basis of support and resistance rather than top and bottom defined by the time required to turn over the float, particularly when, as I remarked in a previous post, the volume traded may not be representative of the float really changing hands in these days of frenetic daytrading.
