“I don't risk significant money in front of key reports, since that is gambling, not trading." - Paul Tudor Jones

When you are trading, the only elements you can control is when to enter a position, where you place your initial stop, your position size and the amount you are willing to risk.

Once you are in a trade, you have no influence over what will happen - the market (being other buyers and sellers) will determine future price direction, and consequently whether your position goes into profit or a loss.

You of course do have control over where you place your initial or trailing stop, but you do not always get out at those prices - particularly if you end up on the receiving end of a price shock and a resultant gap against you. As a result, there is always a risk that you can lose more than your initial risk on any trade.

Earnings releases are, in Rumsfeld-speak, a "known unknown". We know when they will occur, but we cannot predict or quantify their effect on price. Therefore, there is always potential downside risk attached to them. Some announcements may see price move in your favour, others can go against you.

This week we have seen two big-cap Nasdaq stocks suffer large price gaps following earnings releases. The charts of Facebook and Twitter are below.

The futility of predictions

Yesterday I had the misfortune to be copied in on an Facebook thread discussing an impending stock market crash, together with an invitation to join the group who were discussing it. 

This post had more than 200 comments from a number of traders covering the intricacies of the current economic climate and their opinions on this - most of which I didn't understand. 

Idly browsing through those comments wasted ten minutes of my life that I couldn't get back. But it did give me the inspiration for this post.

The rules of the game haven't changed

I started getting involved in trading back in 2003, and didn't get into trend following until 2006. As a result, I missed the huge trends (both up and down) from the dot.com bubble around the millennium.

While thinking idly back to those times, which are now getting on for 20 years ago (yikes!), I began pondering about how things have changed in the intervening period.

Back then, Facebook and Twitter didn't exist. The dot.com bubble sprang from something new to the masses called the internet. Mobile phones were nowhere near as common as they are today.

How on earth did we survive?

And that got me thinking, from a trading and historical viewpoint.

Facebook

US stock Facebook has performed disappointingly since its IPO, however it has now just given its first valid long signal. As with all trades, there's no guarantee that it will generate a profit, but it will be interesting to see how it performs (Disclaimer - I have no position in this).
