Bubble Worries Mean Diversify…. But How?

Mike is concerned that US stocks could be a bubble, as are many others:

if we take parallels to the past seriously, there arises the question of whether a 40 year old with a 100% index fund portfolio should consider hedging/reallocating their portfolio a decade sooner than they planned on becuase, well, just look at that [CAPE] chart.

But what to do about it?

So, seriously. Are we hedging? And what are we hedging into? Asking for a friend. Who is an economist. And also me.

My answer: I’m diversifying into global stocks, which tend to be much lower-priced:

But how do you practically do this?

A simple and cheap way to get a highly diversified basket of global stocks is VEU (Vanguard ex-US). Over 3000 stocks from around the world, P/E of 19, rock-bottom fees. One disadvantage for diversification purposes is that its biggest 5 holdings make up 12% of the index and they are all AI-related.

If you’re willing to make more concentrated and specific bets in order to get even cheaper, here are some other foreign indices I like:

  • FRDM (Freedom 100 Emerging Markets ETF): Invests in emerging markets with the highest economic freedom ratings. I love the theory & it’s performed very well for me & its overall PE is a reasonable 17, though it’s largest holdings are in Taiwan and South Korea, so not a good way to get away from AI.
  • ILF (iShares Latin America 40): Invests in large Latin American companies. P/E 11 with low AI exposure.
  • FYLD (Cambria Foreign Shareholder Yield ETF): Invests in high-yielding companies in developed countries outside the US. Measures yield using stock buybacks in addition to dividends. This serves as a value screen that keeps PE low (currently 13) and avoids expensive sectors like AI.
  • EYLD (Cambria Emerging Shareholder Yield ETF): Same idea as FYLD but for emerging markets. Current PE 12

I also hold single-country indices for Japan (FLJP, PE 20), Poland (EPOL, PE 13), and India (EPI, PE 17). These are probably riskier than the broad indices above, but still fairly diversified across companies.

While foreign stocks are my preferred hedge, there are many others. For US stocks there are small-cap or value indices, or just buying individual stocks you like (not necessarily crazy). The 20- and 30-year US treasury bonds are intriguingly yielding over 5%, though between my age and my inflation concerns I don’t own any. TIPS are much more attractive, yielding 2-3% over inflation, I don’t own any yet but I’m considering it. Gold indices like IAUM are another good hedge.

Of course this isn’t necessarily a bubble that will pop any time soon, or at all- AI is a real technological advance- so between that & general efficient market principles I don’t think the answer is to sell everything & go to cash, much less short the market. But Mike is right to ask how to hedge, and I think anyone holding ~100% US stocks should consider diversifying.

Disclaimers: Not investment advice, I hold some of the indices named.

The Best Investments of the 1970s

The tariffs still have me thinking about buying VIX calls and stock puts (especially when policy changes loom on certain dates like July 8th), and on the bigger question of finding the sort of investments that did well in the 1970’s, another decade of stagflation that was kicked off by a President who broke America’s commitment to an international monetary system that he thought no longer served us.

That’s how I concluded last week. So this week I’ll answer the question- what were the best investments of the 1970’s? When the dollar is losing value both at home and abroad, holding dollars or bonds that pay off in dollars does poorly:

Stocks can do alright with moderate inflation, but US stocks lost value in the stagflation of the 1970’s. Foreign stocks and commodities generally performed better. Real estate held its value but didn’t produce significant returns; gold shone as the star of the decade:

Gold is easy to invest in now compared to the 1970s; you don’t have to mess with futures or physical bullion, there are low-fee ETFs like IAUM available at standard brokerages.

Of course, while history rhymes, it doesn’t repeat exactly; this time can and will be different. I doubt oil will spike the same way, since we have more alternatives now, and if it did spike it wouldn’t hurt the US in the same way now that we are net exporters. Inflation won’t be so bad if we keep an independent Federal Reserve, though that is now in doubt. At any time the President or Congress could reverse course and drop tariffs, sending markets soaring, especially if they pivot to tax cuts and deregulation in place of tariffs ahead of the midterms.

Things could always get dramatically better (AI-driven productivity boom) or worse (world war). But for now, “1970s lite” is my base case for the next few years.
