$10k to invest (not familiar with Stocks but got some help from a relative who's into stocks)

I work in healthcare and have both 401k and Fidelity Pension (work contributes).

I have money acculated here in both accounts. I usually spend my work bonus on vacation/gifts etc but saved $10k as "loose change" from a recent bonus.

Thinking to invest $10k into stocks etc. A relative of mine is heavily into stocks and told me to open up a JPMorgan broker account and then invest into the following starter stocks.

\- Microsoft

\- Nvidia

\- JPMorgan

\- IBM

He said these are the safest starter stocks that can yield some profit within 2 years as these pay dividends on top.

OR should I just move the $10k into my Fidelity Pension OR 401k instead and fuck stocks that seem volatile with the current state of US of A.

TIA!
