Investment Strategies & Mendeleev Principles

Play an AI-generated podcast conversation about this lesson

Which statement accurately reflects the impact of market volatility on long-term investment strategies?

Volatility should prompt immediate shifts to entirely cash positions to protect capital, delaying reinvestment until the market stabilizes.
Effective long-term investment strategies should consider volatility as a normal market dynamic and maintain a diversified portfolio aligned with the investor's risk tolerance and long-term goals. (correct)
Market volatility necessitates frequent adjustments to asset allocation to capitalize on short-term gains, often leading to higher returns.
Long-term strategies should primarily focus on speculative assets during periods of high volatility to maximize potential growth.

What is a critical consideration when evaluating the performance of an investment manager?

Evaluate the manager solely on their use of complex investment strategies and financial instruments.
Focus on investment managers with the highest advertising budget, as this indicates that they are a reputable investment management firm.
Assess the consistency of the manager's performance relative to their stated investment philosophy, benchmarks, and risk-adjusted returns over a complete market cycle. (correct)
Primarily focus on the manager's ability to outperform market benchmarks in short-term periods, as this indicates superior skill.

What role does behavioral economics play in understanding investment decision-making?

It focuses on mathematical models that predict market movements without considering human behavior.
Disregards the impact of psychological biases.
It explains how psychological biases and emotional factors can lead to irrational investment decisions, impacting market efficiency. (correct)
Behavioral economics assumes investors are rational and make decisions based on perfect information.

Which factor poses the MOST significant challenge to achieving consistent, long-term investment success?

Periodicity (in elements)

A repeating trend in elements' chemical and physical properties when arranged by atomic mass.

Mendeleev's contribution

Ordered elements by atomic mass and noticed periodicity; left gaps for undiscovered elements.
