Blue-chip companies are well-known for their stability and resilience.

However, not all such companies are built alike.

Some may see their business floundering while others may experience stagnant revenue or profits.

That’s why it’s important to look for catalysts, even when investing in large, reputable businesses.

These catalysts may come in the form of a strong recovery from a downturn, acquisitions that help to power growth, or strategic initiatives that enable the business to build for the future.

Patience is also a necessary ingredient for successful investing.

Time is needed for these catalysts to come through and lead to an increase in revenue and profits.

Here is a list of three blue-chip companies that you can add to your investment watchlist.
