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 Kulicke & Soffa Industries (NASDAQ:KLIC) jumped more than 10% in Tuesday's early trading, then settled to close up around 8% after the semiconductor and LED assembly equipment specialist turned in better-than-expected fiscal second-quarter earnings and strong forward revenue guidance.

So what: Quarterly revenue rose 7.6% year over year to $114.2 million, which translated to net income of $0.12 per diluted share. Analysts, on average, were looking for net income of $0.11 per on sales of $115 million. 

In addition, Kulicke & Soffa expects current quarter revenue to be in the range of $165 million to $175 million. By comparison, analysts were modeling fiscal third-quarter sales of just $154.42 million.

Now what: Kulicke & Soffa CEO Bruno Guilmart added: "We have experienced strengthening demand in the majority of served markets and expect this trend to continue throughout the June quarter. We look ahead with great optimism as we continue to actively enhance our core market positions, expand in adjacent areas through organic development and pursue meaningful external growth opportunities."

With shares currently trading at a reasonable 19.4 times last year's earnings and 15 times next year's estimates -- and keeping in mind those estimates are likely to drift higher as analysts have time to fully digest today's news -- I think the stock should have no problem continuing to reward long-term shareholders from here.

The biggest thing to come out of Silicon Valley in years
