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 Harbin Electric (Nasdaq: HRBN) jumped 10% this morning on extremely high volume.

So what: With two hours left in the trading day, 2 million shares have already traded hands -- nearly five times the average daily volume. Investors are hoping a buyout offer for the company comes sooner than later, but we've been waiting for it for weeks.

Now what: Harbin did file a SC 13D with the Securities and Exchange Commission today, and investors are betting a firm offer is coming soon from a management-led buyout. It's possible this will happen, but it's still too risky for this Fool to jump in. We've heard rumors like this before, and nothing has come of it yet.
