INTC data by YCharts

What: Shares of Intel (NASDAQ:INTC) gained 12.3% in October, according to data from S&P Capital IQ.

So what: Intel's stock is always swimming through a ton of market-moving noise, and October was no exception. The semiconductor giant started the month on a strong note, rising 10% on nothing more than PC market reports and a lack of economy-related panic in China.

Intel reported third-quarter results without moving share prices very far.

Then, on October 19, Intel boosted fertility and adoption benefits for its 167,000 workers, and also said it would spend $5.5 billion to turn a Chinese processor factory into a memory chip facility.

These moves unlocked a quick 4% gain over the next two days. In my neck of the woods, we call that a difference-maker.

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.

Now what: It's hard to say which one of those mid-month moves carried the most market-moving power. So let's consider them together.

The common denominator here works out to management having a high level of confidence in Intel's current and upcoming business prospects. You don't make a $5.5 billion capital investment on a whim, even if you have $21 billion of cash on the balance sheet. And you don't quadruple a worker benefit if you don't need them to stick around.

The memory-plant upgrade could make Intel a serious supplier of NAND flash-memory chips, churning out as much as 7% of the global NAND supply. However, Intel is also a longtime partner with memory expert Micron Technology (NASDAQ:MU), and might simply use the Chinese factory under the banner of its Micron joint venture.

Either way, the immediate takeaway remains: Intel is not afraid to spend a few billion right now if it helps the company stay relevant for the long haul. October's market-beating gain was a vote of confidence from investors and management alike.
