I will play devil's advocate one final time, and you can have the last words on this subject
" that means he beats 99% of the investors/traders/money managers out there. "
I guess that puts me in the 1%
Now this is Elite
TRADER and not Elite Investor, right

So let's forget about investment yard sticks and talk about trading yard sticks. If you have a copy of my book The Stock Trader handy, you can see that I made a 56% return in 30 days in a market that went down 32% trading ONLY on the long side. All this while sweeping profits out of the account weekly and never compounding profits. Although my approach was aggressive, I feel that the risk management was not reckless.
Now let me tell you this straight out and in public! I feel that I could have at least doubled if not tripled my return for that time period have I been able to trade BOTH sides of the market!
You see, this is the beauty of TRADING. We are not looking to invest one way only. We want to take advantage of the market NOW - Both long or short.
You say, "A portfolio that has quality returns such as Shortboy's, that outperforms 99% of ALL portfolios, and then add that his trading strategy is VERY LOW risk (he hasn't has 1 single day in almost 3 years where he's lost 2% in a day!! and you add it all up, and you have a winning trader who can sleep at night (low risk). And that's about the best type of portfolio anyone (including you), would want."
First, shortboy has no track record performing in a bull market against long funds. So, given the bear market he did well. Yet, there are bond funds, global funds and other historically weak funds that SMOKED him in the same 34 months. But historically, those funds ranked in the bottom 20%. So you need a lot more time if you wish to compare shortboy to his peers.
Next, the best performing fund over the last 5 years is up 40% annualized. Yet it did not perform as well as shortboy in the last 34 months. But it will smoke him in any bull market environment.
Finally, and mark my words,
the bull market created a lot of geniuses, and the bear market has created shortboy. Once the bull is back, you can kiss shortboy goodbye. There is no way he could keep up trading only one side of the market.
And as a bonanza, I will force you to answer the question that you ignored.
"Without taking anything away from shortboy.com's performance, education etc., wouldn't you agree that it would be beneficial to a trader to master the art of playing BOTH sides of the market?"
If the answer is yes, as it should be, this puts an end to the value an evolving trader can get from a narrow-vision approach such as exclusively shorting the markets. Sometime, I like to order the Lobster rather than the Filet Mignon...

PS: I only used my personal performance yard stick to illustrate how a trader can take advantage of the market trading on both sides. The difference at that 1% bracket Sam referred to is HUGE. If I were to pay someone for TRADING advice, he better know how to take advantage of the SWINGS in the market. As far as investment arguments are concerned, I would like to point you to the name of this website.
PS2: Sam, as an investment and diversification or whatever tool you may want to use this approach for, it may be valid. But, as a long timer in this industry, I don't see the long term value to a trader to mimic a narrow-minded short-only approach just as I don't see the long term value to mimic a narrow-minded long-only approach. Why not have the Lobster and the Steak
