Don't place an order the moment the news breaks; wait for the candlestick chart to develop before deciding.
Take this as an example: A whale that had been dormant for a year sold ETH and stETH worth $6.357 million during a rebound.
Whether more authoritative media outlets confirm it next is what determines how much weight to give it.
$ETH is currently at 2429.05.

Just chatting—this isn't financial advice.
