Quite unrelated, I have been wondering whether the short selling data on aastocks are a reliable indicator of the short term movement of a stock price.
For example, Agile Group (3383) shows a 25.7% short selling ratio, which seems to be a big number, and the price did drop by 2.46% yesterday. HSBC has a smaller short selling ratio, and the price dropped by less. On the other hand, 3988 has a higher short selling ratio and no price movement yesterday. I used to look at it when I stocked up on REITs, and I think it did help me to save some money, but I don't know how reliable it is in general. Is anybody using it when trying to time a stock purchase?
