You’ve probably seen the headlines recently:

Stocks slide on Brexit fears

Dollar slides as Brexit fears dominate markets, and

Australian share-market turbulence fuelled by Brexit fears,

I get it. There’s fear out there (or there was on Tuesday at least).

As usual, short-term traders adopt a myopic view on currency/share markets and ‘sell the lot’ as the UK electorate looks to vote in the European Union membership referendum on 23 June 2016.

I’ve seen all of this market turbulence before (anyone remember the US subprime crisis of 2007, the Lehman Bros collapse in 2008 or the first Greek bailout in 2010?).

Yet again though, the market is (possibly) serving up opportunity dressed up by the media as risk.

I say possibly because I don’t know if the falls are going to continue. Perhaps they will and of course, if they do, then I’d become very interested as a stock buyer.

Of course, if you’re a long-term investor, buying stocks after they’ve fallen and at a discount to their real worth is usually a profitable strategy, especially if you’re not looking to sell your stocks soon after, but rather stick to a long-term strategy of business ownership.

Here are five great stocks that should be on your watch list now. If these stocks fall dramatically then the opportunity to own shares in these businesses should be too lucrative to pass-up:

Commonwealth Bank of Australia (ASX: CBA)

I’ve previously written why I don’t like any of the banks, but that’s at current prices. Banks face a lot of challenges what with slowing lending growth, higher capital requirements and the potential for higher provisions for bad and doubtful debts.

In the CBA’s case too (the largest company on the ASX by market capitalisation), there’s also the not-so-small matters of financial planning and life insurance scandals which have hit the bank’s reputation recently.

It’d take a much lower price for me to be interested, and for me, I’m talking about $45 or lower. Does this sound ridiculous? It could be until you realise that when markets move irrationally, they really move. The CBA fell below $28 during the GFC which was completely unreasonable to rational people who saw fair value between $50 and $75.

But rationality gets thrown out the door in times of market turbulence when people all try to exit the stock at once.

The CBA is a quality bank and I’d gladly pick up some shares at a major discount to where it’s trading now. A low price can cure all ills.

Sydney Airport Holdings Ltd (ASX: SYD)

With international travellers passing through the airport’s terminals increasing, helped in part by record-low ticket prices and a lower Australian dollar, this is a stock to own for a very long time.

Just not at the current price of just north of $7 though.

It has a dominant market share for travellers entering and exiting the country, helped along by a profitable car-parking and shop-leasing business on the side.

I don’t know if a Brexit-induced market meltdown would ever cause its price to drop dramatically, but if it fell to below $5, I’d be an interested buyer.

Transurban Group (ASX: TCL)

As official interest rates have steadily fallen, stocks like Transurban have become increasingly attractive for yield-hungry investors.

Which is why there’s a problem with buying this stock today – it’s expensive.

On a mostly-unfranked yield of 3.6%, the yield looks attractive when compared to official cash rates and there’s a lot to like about this stock; steady revenue, good cash-flows and a strong competitive advantage.

With dividends and earnings forecast to grow by close to 10% over the next two years, there’s no near-term catalysts for this stock to be re-rated, unless the market decides to throw everything out the window and this stock with it.

Here’s hoping then for some irrational indifference to this stock in a market-wide cataclysm that can knock its price below $7.
