It is one thing to see how these events have influenced the price when you are looking back and entirely different to work out possible impact in real-time.

For me this is the right place for that. Bitcointalk is very useful tool if you wish to earn on trading. Before any purchase I come here and search for interesting things about some specific coin. I know there is a lot of comments, but if you know what you searching, have a bit patience to read all stupid things first you will find very good comments from people who have some very valuable information's.
Here you can always open some topic and ask what ever you wish, just before asking something first take a look on other threads, maybe someone had same question like you..

if you are looking for something that gathers all the information in one place and then analyze it for you then i have to tell you that you are out of luck because it is all scattered and not all the information you might find on the social media is correct, a lot of them are lies and false information trying to pump a coin.

all you need to know about altcoins are gathered at coinmarketcap.
click on each coin name or search for them to see the charts from the beginning of the time.

also on top of the chart there is 3-4 link to the bitcointalk announcement thread, the coin's official website and twitter if available.

you can also see in which exchangers they are being traded with what volume, what else do you need?

Try the following:

I like it for monitoring transactions in the last 24 hours. If a competitor to BTC shows up it will be in the transaction data first.

Coingecko is good for monitoring the social reach of an alt (though some of their stats can be manipulated, eg fake tweets, fake reddit subscribers and so on)

Avoid ALL services by ocminer and icocountdown like the plague. They are both the braid dead offspring from a long ancestral line of idiots. They are like the two scumbags that turn up to every party only to stand in the furthest corner the whole night and perv over all the girls because they are porn addicts and social deviants

For analysis and news, the charts are your friend. For information regarding the release of new projects, see the announcement section of this forum. For mining: just don't, if you don't have powerful rigs of your own then investment into other areas is the way to go

I personally keep track of information on this website: http://coinmarketcap.com/

you are unaware of google.com go there and search what you need,

for bitcoin news you can check out coindesk it also has a price section with a nice chart of most of the exchangers.
for price and charts you can visit bitcoinwisdom.com
for altcoin price and charts you can visit coinmarketcap.com

p.s. the news and rumors may not be as powerful as you might think.

There are lots of places like crypto blog like coindesk, newsbtc, twitter handler of well known traders, speculation thread and altcoin discussion category in this forum. You will not find one place with all the info about what to buy and what to sell.

And if it is the market data (prices, volumes) you are after, the best and most comprehensive source I know is http://www.bitcoinity.org/

I recommend http://www.coindesk.com/news/
