Although we don't believe in timing the market or panicking over market movements, we do like to keep an eye on big changes -- just in case they're material to our investing thesis.

What: Shares of independent oil and gas company FX Energy (NASDAQ:FXEN) fell 19% today after updating reservoir results.

So what: The Tuchola field in north central Poland was found to have 20 billion cubic feet of gas in a dynamic flow test, but management warned that a pressure buildup "could indicate a somewhat higher figure." It's estimated that 60% to 65% of the gas will be recoverable.  

Now what: Results appeared to be in line with what management announced earlier, so the reserves shouldn't be an issue. It could be that investors were expecting production before the end of 2016, which is the earliest management expects production. That's a long time to wait for revenue and is reason to be cautious since analysts don't even expect FX Energy to be profitable this year or next.
