The best news source for instant news is a Bloomberg Terminal, for about $1,800 per month.
The best way to get instant news free is to watch CNBC on TV.
Your question just begs another question: "Can you trade the news?" Most cannot. It is a specialized situation with high volatility and high risk, not something the average investor should use for decisions or entry. But alas, the media tells us differently, that only they "know" the real story. Or an "expert" tells us something only he knows, but he doesn't tell us 90% of funds and "experts" can't beat the market average they follow.
The EMH (Efficient Market Hypothesis) more or less argues that all available information is already priced into the market, and that any new news is efficiently, effectively, and immediately reflected in price; thus, zero opportunity.
Certainly there are big news events, game-changers that last for months, like a big earnings miss or a new product or war. But most daily news will not be recognizable on a chart a few weeks from now.
Essentially, when you chase the news and the "why" of everything, you're saying that if you "know" something, then you can predict the future. Think again. Not one single person, ever, has been able to predict future price or direction or extent any better than a coin toss. Worse, the news leads you down the wrong path, ignoring what is really relevant, thinking you "know" something about the future. And if you "know" direction, why bother to use stops or learn anything more? You are stopped dead in the tracks of becoming successful, and the news has become detrimental. Turn off the news and focus on something relevant. Opinion is not relevant.
Even if you "know" the news in advance, you still do not know the markets reaction to the news. It's really a lazy man's way to pick stocks -- to let someone else tell you which ones are best. It's the story that is captivating, but almost useless as an entry point. There are lots of better ways to pick and value stocks. The news can give you ideas and starting points, but is more parlor banter than a tool or basis for knowledge. News or opinion is an anti-thesis.
If the news is your primary objective and excuse for knowledge, then you are ignoring what should be your primary objective, which is to manage risk. Your entry determines and fixes risk. Position size is according to the risk/reward ratio. Risk determines where you place your stop, or if the trade meets the criteria of your trade plan. All money management techniques used are defined by risk.
If you are chasing price on the news, you are ignoring good trading strategy, and will get a horrible fill at an extended price with incredible risk, almost guaranteed to be challenged on a pullback in a big way. A successful trader/investor does not set themselves up for huge losses. What could possibly be worse, what could possibly go more wrong, than trading the news without advanced knowledge of how to do that and without a tested trade plan for that specific incident?
maybe market watch ? not sure though.
Have you checked your brokerage? They usually offer this functionality.
I am looking for a website that will alert you when any news comes out about a certain stock. I signed up for all the watch lists: Bloomberg, Yahoo, WSJ, Motley Fool, but they don't seem to alert you when current news comes out.
Does anyone know of any free sites that offer this? Thanks!
