Forget the golf clubs! We have some great investment ideas Foolishly wrapped up in this special series for Father’s Day.

My father taught me the importance of stretching a buck. With Father's Day just around the corner, I guess I'll return the favor by introducing him to closed-end funds.

I'm not sure why closed-end funds don't get more loving out of investors. The market loves conventional open-ended funds. We even have a newsletter service dedicated to singling out the best ones. Exchange-traded funds -- or ETFs -- are the flavor of the month. So why aren't closed-end funds more popular, especially since they're a way for thrifty investors to buy into a basket of equities for pennies on the dollar?

Closed-end funds are actively managed funds that trade on exchanges. Because market sentiment dictates how the share price fluctuates, you will often find funds that trade for less than net asset value (or the value of all of the fund's assets, divided by the number of shares outstanding).

Another advantage to closed-end funds is that they don't have to print out new shares when investors buy in, nor do they have to sell assets to cover redemptions. Closed-end funds have a fixed number of shares, so they give managers greater peace of mind in their asset allocations.

Where was I? Yes, bargains. Here are a few closed-end funds trading at wide discounts to their NAVs heading into this week.

Adams Express (NYSE:ADX)

Petroleum & Resources (NYSE:PEO)

Templeton Emerging Markets (NYSE:EMF)

(7.5%)

Adams Express has stood the test of time. The fund has been around since 1929. Its largest holdings include plenty of blue chips you're familiar with, with General Electric (NYSE:GE) making up 4.1% of its assets, and Microsoft (NASDAQ:MSFT) and Schlumberger (NYSE:SLB) at 2.6% each.

In sum, you can buy a basket of stocks worth $14.57 a share for $12.61 as of the market's close on Friday.

As its name implies, Petroleum & Resources specializes in energy stocks. Most of the holdings center on oil, with ExxonMobil (NYSE:XOM) accounting for a thick 11.3% of the fund's portfolio. Petroleum & Resources is the largest holding for Adams Express, at 6.3% of net assets. I guess that makes Adams Express a way to double-dip into the discount, yet investors may still be attracted to a pure sector play in a hot commodity.

My final pick is Templeton Emerging Markets. The Templeton fund family is a pioneer in international investing, and I believe that mutual funds -- especially closed-end funds trading at a discount -- are a great way to get proven managers picking holdings in fast-growing emerging markets.

So there you have the three bargains. Let's hope that will whet your appetite to check out the hundreds of other closed-end funds that currently trade at attractive discounts.
