In the monthly charts below – FOXA, CMCSA and TWX – you can see which media giants are leading or lagging each other: all are at or below their respective major resistance levels.
The only one whose momentum indicator is above zero on this long-term timeframe is FOXA. And if it plunges and falls below zero, no doubt the others will weaken further.
On the flip side, if FOXA breaks and holds above its prior swing high of 39.27, the others may gather strength.
