The number of people living with Alzheimer’s disease is growing. The ripple effect is straining families, communities, and the healthcare system, yet talking about the disease on a personal level can be difficult.

November is Alzheimer’s Awareness Month because it can happen in any family, and because it’s worth talking about the challenges of living with or caring for someone with this disease.

You may notice splashes of teal and purple sprouting up this November, as both colors are associated with Alzheimer’s awareness. Teal is the color of the Alzheimer’s Foundation of America, chosen for its calming effect. Purple is the signature color of the Alzheimer’s Foundation, which stands for strength in the fight against Alzheimer’s disease.

George Boole, an English mathematician from the 19th century, developed an algebraic method that he first described in his 1847 book, The Mathematical Analysis of Logic and expounded upon in his An Investigation of the Laws of Thought (1854).

Boolean algebra is fundamental to modern computing, and all major programming languages include it. It also figures heavily in statistical methods and set theory.

Today’s database searches are largely based on Boolean logic, which allows us to specify parameters in detail — for example, combining terms to include while excluding others. A Boolean search, in the context of a search engine, is a type of search where you can use special words or symbols to limit, widen, or define your search.

This is possible through Boolean operators such as AND, OR, and NOT, plus symbols like + (add) and – (subtract).

When you include an operator in a Boolean search, you’re either introducing flexibility to get a wider range of results, or you’re defining limitations to reduce the number of unrelated results.

DEDICATED: Short Stock Bias Strategies

Dedicated short bias strategies short stocks expected to depreciate as a result of company-specific catalysts or falling markets. These strategies maintain a net short exposure to the equity market, seeking to reduce equity portfolio volatility and offer the potential to earn returns in falling equity markets. Of course, they may be challenged in periods of rising equity markets.

From Shorting to a Short Bias

Prior to the long-term bull market for U.S. equities that took place in the 1980s and 1990s, many hedge funds used a dedicated short strategy, rather than a dedicated short bias strategy.

The dedicated short strategy was one that exclusively took short positions. The dedicated short funds were virtually destroyed during the bull market, so the dedicated short bias fund emerged and took a more balanced approach. The long holdings are enough to keep losses manageable, although funds can still run into problems with leverage and capital flight if losses continue for too long.
