I have been using a modified form of his ideas for a few months, with good success. I use etfs only, and primarily commodity, bond, currency and real estate etfs--not too many stock etfs, other than those that are commodity based. Stocks do not trend as nicely as other assets. Look at forty or fifty charts of different types of etfs and some stocks and indices and I think you will see what I mean. My rule to enter is that the etf must cross the 200 day and also be above the 50 day, and the 50 day must be increasing. I exit when the 50 day starts decreasing or the etf falls below the 200 day. I do the opposite for shorts: sell when the etf crosses the 200 day and the 50 day is falling (note that this is not the mirror image of my long entry method; here I do not require that the etf be below the 50 day). Buy in the short when the etf crosses back above the 200 day or the 50 day starts to rise. So I am only initiating a trade at the 200 day sometimes: when the 50 day tells me to. And I am not waiting for the 200 day to tell me to get out, I'm using the 50 day for that. Where did I get these rules? I made them up after looking at many charts going back several years. They seemed to me to be a reasonable balance between whipsawing and holding too long. Using the 50 day rule cuts down substantially on the whipsawing. (A similar 100 day rule works almost as well.) There is still some whipsawing, so I don't go 'all in' on the first day. I buy and sell over a two or three day period of time. Occasionally there is a reversal and I never end up taking a full position, or even end up exiting everything within a few days. In addition, I use a deep discount broker who charges one dollar for 100 shares. Generally speaking, almost anything trends better than stocks. Some the etfs I've worked with are IYR, XLE, DBC, DBA, MOO, CUT, KOL, DBB, FXY, FXA, FXB, FXF, IEF. I check my positions as well as other etfs I'm interested in each evening and make a plan for the following morning's open. After some honing and practice, I can look through my list of about 70 etfs in about 10 minutes. I think you could just as well check the list once a week or once a month, as long whatever time frame is used is consistent. While my results are good, I think it is important to keep in mind that the market is in a hell of a trend, and also that at the present time, nearly everything is trending upward, that is, nearly everything is correlated. Things will not always be so trendy or so correlated. I can see from charts that for any etf, there will sometimes be entire years that consist mostly of whipsawing. Needless to say, nothing works all the time. Another problem is that some of the less liquid etfs do not lend themselves to shorting. For example, I tried to short DBB at one point, but the broker was unable to borrow the shares. Therefore, one would need to either stick to larger etfs to short, or else forget about shorting and hold cash when conditions so dictate. I can't comment on the advisability of shorting versus holding cash, as Faber does. I have only been doing this since April and there has not been much to short! I have made 9.2% using this method since April and have spent 0.6% in commissions. While this is substantially less than the stock markets have returned, I have done this with considerably less risk.
