Exited the Short on the S&P 500

At the today’s close my system indicated a neutral position, which was quite timely since I will be away for a while, unable to trade.

Went Short on the S&P 500

Looks like I forgot to disclose my long entry, but I was long since the close of June 17th. Today my artificial brains are reversing their short term view on the S&P 500 and I acted accordingly at the close.

Closed the Short on the S&P 500

The market went against this short right from the start. Things got better today, nonetheless my system thinks it’s time to stay out of the index until the next long signal arrives.

Max-Sharpe Allocations for June

The strategy implementation was posted originally on the Systematic Investor Blog. May’s allocation was good for a 2.4% gain.

The allocations for June differ, but only slightly, between the original approach and my modified version:

ETF Original Modified
S&P 500 (SPY) 33% 28%
Emerging Markets (EEM) 20%
US Bonds (TLT) 55% 52%

Both strategies have more than 50% in bonds, not surprising at all considering the recent rally in bonds. Both strategies also have about a third in US stocks, but while the original strategy favours EFA (MSCI EAFE – Europe, Australia, Asia and the Far East), my modified version prefers to stick with the emerging markets. Most likely these differences will prove insubstantial.

Went Short on the S&P 500

Time to switch gears again. If it seems too quickly – that’s because the trades are making money.:) Glad to note, that my intuition was wrong about the previous long positions – it turned out to be quite timely, in fact.

Entered a Long on the S&P 500

At the today’s close I took the long side yet again. My gut feeling is that it’s a bit premature, but a hunch is not sufficient to make me overwrite the system. Don’t take me wrong, there are situation when I take discretionary actions, but these situations are usually well defined in advance, in a way, they are part of the system. It may seem extreme, but I’d do anything to keep the emotional brain out of the equation.

Closed the Short on the S&P 500

Closed the short at the today’s close, but the system didn’t signal any new position. Staying out for a few days I guess.
