As an equity portfolio manager at a mid-sized investment firm, you aim to leverage both fundamental analysis and behavioral finance in your investment strategies. The firm has recently been evaluating the impact of investor psychology on stock prices, particularly focusing on phenomena such as overconfidence, herding behavior, and loss aversion.

Discuss how these behavioral biases could influence an active equity investing strategy. In your response, address the following aspects:

1. Identify and explain at least two behavioral biases that can negatively impact investor decision-making.
2. Describe how these biases might manifest in the stock market and affect stock prices.
3. Outline actionable strategies that you could implement to mitigate the impact of these biases on your investment process.

Provide examples where relevant, and structure your response clearly to demonstrate your understanding of behavioral considerations in active equity investing.
