altcoins defying logic

Why are altcoins defying logic recently? Normally partnerships and news would lead to increased value, for example vechain partnering with BMW, litecoin implementing litepay, neo offering Airdrop, icon releasing it's mainnet, tron announcing mainnet plus coin burn, etc should be reason for increased value and spike in buying of coins but recently the news seems to do the opposite, like across the whole market it seems that coins that were already dipping release news that should make their price increase and as a result the dip they were already experiencing becomes a big dump. It's almost like great news for a coin is affecting it like fud. I know we are in a bear market, but shouldn't good news have a positive impact on coins? Instead the whole market seems to p&d a new shit coin every day based on absolutely nothing
