The Federal Reserve's all-important policy meeting this week is going to affect where investors put their money to work going forward.

The Federal Open Market Committee, which will conclude its two-day meeting Wednesday, could start preliminary discussions about scaling back the unprecedented bond-buying programs that aided the economy during the pandemic.

Some market participants believe it's still too soon for the central bank to signal such a tapering action, while others think the Fed will be able to find a happy medium that won't upset the markets.
