Quote from u21c3f6:
There is no paradox.
The object is to buy low and sell high. The individual investor decides the %'s that he/she would like to attempt to capture.
This is not a perfect science so you have to allow room for costs, mistakes (losses) and still allow for a "good" rate of return.
Joe.
But you are not operating in a vacuum. You have your cash balance earning 2% in t-bills. You have prospective investments which, at a price, will earn more than 2% + the appropriate risk premium to justify owning the stock.
As soon as the stock falls 1 tick below the level sufficient to generate a return of 2% + the risk premium, surely a value investor must buy? Since the investment will be superior to cash, it would be irrational not to buy.
Then, let's say the stock moves up 2 ticks. The investment is now *inferior* to cash - isn't the rational value investor compelled to sell out and put the money back into cash?
As I said before, having a very large risk premium (e.g. the Graham and Dodd 50% discount) simply lowers the price at which a value investor is logically compelled to buy - and then sell 2 ticks higher.
