In the past five business days, the S&P/ASX 200 (Index: ^AXJO) (ASX: XJO) has fallen four times and looks headed for another disappointing day today, with the market down 0.1% in early trading.
And already we are seeing some market commentators predicting the theme will continue for the rest of the 2016 year.
But here's why you need to totally ignore the market's movements over the past week.
A week does not a trend make
Just because the market falls for four of the first few days of the new year, that doesn't mean much, and the market could soar higher from here or crash much lower in 12 months' time. No one knows where the market will finish the year.
Big companies dominate
The Australian market is dominated by the big four banks Australia and New Zealand Banking Group (ASX: ANZ), Commonwealth Bank of Australia (ASX: CBA), National Australia Bank Ltd (ASX: NAB) and Westpac Banking Corp (ASX: WBC), Telstra Corporation Ltd (ASX: TLS), BHP Billiton Limited (ASX: BHP), CSL Limited (ASX: CSL), Wesfarmers Ltd (ASX: WES), Woolworths Limited (ASX: WOW) and Macquarie Group Ltd (ASX: MQG).
Those 10 large caps represent just over half the market cap of the entire ASX 200 index, and factors that affect them will play a large part in where the index goes. In particular, the big four represent 30% of the index and are now our 4 largest companies, so whether the index falls or rises depends much upon the outlook for the banks and their earnings in the year ahead.
No individual company tracks the index performance
If you are investing in individual companies, you shouldn't be all that concerned with what the index is doing. In 2015, the S&P/ASX 200 posted a fall of 1.9% according to Google Finance, while shareholders in Blackmores Limited (ASX: BKL) saw gains of 538%. Do you think they cared what the index was doing?
Be more concerned about the performance of your individual shares than the overall market.
Foolish takeaway
Concentrate on investing in high-quality companies that can grow earnings over time, invest regularly (including your dividend payments) and avoid the potential ticking bombs like Slater & Gordon Limited (ASX: SGH) and real bombs like Dick Smith Holdings Ltd (ASX: DSH).
