But as a fundamental investor, I only invest in companies I deem to have an attractive price to value proposition. If I shorted shares (which I don't), at $43 xro would have been a good bet at more than 100x revenues. From there, the fundamentals kept getting better and yet the price plummeted. So tell me, how would you possibly know when to buy or sell?

They way I see it, I've kept my prescious capital away from a risky, loss making investment and used it to invest in higher quality, profitable and valuable businesses.
