Don't get me wrong, I think diversification is very important. But massive gains can be made by getting just a few picks dead-right. Buffett knows this.
I've trawled the market to find a collection of high-yielding shares. The drawback is that my portfolio below contains just a few shares and is heavily biased toward insurance.
||Yield (forecast, %)
||Market Cap (millions of pounds)
|Aviva (LSE: AV )
|ICAP (LSE: IAP )
|Resolution (LSE: RSL )
|RSA (LSE: RSA )
|Vodafone (LSE: VOD )
Resolution is the big beast of the dividend world. The 800-pound gorilla. Resolution owns Friends Life, a provider of insurance, investments, and pensions.
Resolution is forecast to pay 20.9 pence of dividends for 2012. At today's price, that puts the shares on an 8.4% yield. Normally, cautious investors wince when they see a yield like that. They assume that the payout is a one-off or that it cannot be sustained in the long term.
This will not be the first time that Resolution has ponied up a big dividend. In fact, the payout has been increasing at the company since 2009. Analysts are forecasting that it could even rise further for 2013.
The yield is covered by earnings. That 20.9p would be paid out of 23.7 pence of expected profits per share.
Markets have recently been cheered by the company's reorganisation of some of its debts. This will save Resolution money, increasing the probability that the large payout can be maintained.
RSA is the company behind the MORE TH>N insurance brand. For a number of years now, RSA has been one of the biggest yields in the FTSE 100 (UKX).
The dividend payout at RSA has been increasing year over year since 2006.
Shares in RSA have risen 13.4% in the last month. This has had the effect of pushing the dividend yield lower. Current forecasts are for earnings of 11.5 pence in 2012 and a dividend of 9.34 pence. In 2013, those figures are expected to hit 13.4 pence and 9.55 pence respectively.
If more investors believe in those forecasts, then I expect that the RSA share price will move higher.
Of course, any hit to profits could be very bad news indeed. With cover looking so thin, a dividend cut would become more likely.
Aviva is the third insurance specialist to make my concentrated high-yield portfolio. It is also the company whose dividend investors worry about most.
The Aviva dividend was held at the interim stage. Given that consensus expectations are for a fall this year, clearly some analysts are expecting Aviva's next statement to confirm a cut.
Aviva's management have outlined a series of changes that could lead to 400 million pounds in cost savings. If Aviva can remove these costs and maintain profitability, the dividend will be safe.
I worry when companies need to cut costs to maintain profits/dividend. Why is the business no longer as profitable? If a company can manage without rafts of staff/systems, what were they doing there in the first place?
ICAP is another company planning major cost cuts to improve profitability.
ICAP is an inter-dealer broker. This is a niche within the financial markets. ICAP acts as a middle-man between customers who need to trade securities at a competitive price.
ICAP has made itself the market leader in the field. The company's success saw it grow annual revenues to more than 1.5 billion pounds. ICAP was, until recently, a FTSE 100 company.
As activity in ICAP's markets has declined, so have analyst expectations on what the business could achieve. Today, the consensus opinion is that ICAP will deliver earnings per share (EPS) of 33 pence for 2012. This time last year, expectations were for 41.1 pence in earnings.
Investors will be hoping that savings in the business and a return to more buoyant trading will secure the dividend for the future.
Vodafone has recently announced that it has begun a 1.5 billion-pound buyback of its own shares. This is the company's way of spending the payment it recently received from Verizon Wireless, its joint venture with Verizon Communications.
Vodafone has already committed to spending 550 million pounds buying back shares between 10 December and 20 February. I had been expecting the entire buyback to push Vodafone's share price higher. After all, 1.5 billion pounds is good for almost 2% of the company at today's prices.
Even without a short-term rise, there are still reasons to hold. At the interim stage, the Vodafone dividend was increased by 8.2% to 3.27 pence per share. If the usual weighting between interim and final dividends is maintained, then Vodafone shares are set to yield 6.2% this year.
