I'm not sure how PE ratio is calculated by Market Scan, but am aware that some sources base it on current earnings while others do it future earnings. The may explain the differences noted in your mail.
I think this boils down to an issue reported elsewhere on the forum.
The data is way out of date. If I dig out BPT's 2005 EPS value of 5.6 and plug it into the Price/EPS I end up with 1.35/0.056 = 24.107 pretty close to the 25.28 reported by MarketScan
Conclusion - the data is out of date and you would have to seriously question the relevance of any scans.
yes, can someone tell us how market scan really works. like sample computations will be appreciated. this is just to make sure the system really works efficiently, ive been using a different system and planning to switch it to market scan.
