- Diversification: Balance exposure across sectors (media, tech, telecom) to mitigate volatility.
- Timing: Consider entry points near key catalysts (e.g., earnings upgrades, partnership announcements).

In a market where small-cap stocks are often overlooked, these picks offer a compelling blend of value and growth potential. As always, align investments with your risk tolerance and time horizon.
